1. Puzzle & Action: Ichidant-R (Arcade via MAME) 1/1
2. Detana!! TwinBee (PC Engine) 3/7
I haven't had the time to finish off a handful of games I started in 2015, let alone seriously start something new (though there is one game I started in 2016 that I'm close to beating if I can just get back to it), but I gave my PC Engine Duo-RX some love after barely touching it the last few years. Played all the way through my old favorite Detana!! TwinBee, though on Easy and most of the way with two players (cleared the last stage by myself).
